GLIDE: 2HP glide/portamento buffer with illuminated fader

A 2HP reimagining  of one of my first ever modules - a glide/portamento buffer.

Due to the limitations of the 2HP form factor this is only a single channel unit, but it uses an illuminated fader to control the glide rate and the LED on the fader reflects the outgoing voltage^*, which can lead to some interesting visual effects.

A typical use case would be applying some portamento to sequencer output, but it can also be used as a basic envelope generator on the understanding that both attack and decay times will be approximately equal. Finally, there's a switch on the rear of the board which allows the glide rate to be altered between 'long' and 'short'

Supplied with an FR4 panel, mounting hardware and power cable.

^* - the LED in the fader has a forward voltage of around 2V, meaning that it will not illuminate if the incoming voltage is less than this, although the signal will still be slewed.
